- Genetically modified bacteria were the first organisms to be modified in the laboratory, due to their simple genetics.These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine.imilar bacteria have been used to produce clotting factors to treat haemophilia, and human growth hormone to treat various forms of dwarfism. These recombinant proteins are safer than the products they replaced, since the older products were purified from cadavers and could transmit diseases.

Creating solutions for health and nutrition Recombinant DNA technology provided a way for scientists to produce human insulin in the laboratory. The gene for human insulin is isolated from human cells and inserted into plasmids. These plasmids are then introduced into bacterial cells, which manufacture the insulin protein based on the human code.n addition to bacteria, other biotechnologists use yeast in recombinant DNA technology to make human insulin. Yeast can perform more of the complicated cellular processes that occur in human cells, making it a more useful organism for producing human substances.

Transgenic Organisms Modern genetic technology can be used to modify the genomes of living organisms. This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Most transgenic organisms are generated in the laboratory for research purposes. For example, “knock-out” mice are transgenic mice that have a particular gene of interest disabled.

- Next. Genetic engineering can be used to create organisms that produce large amounts of useful substances-for example, bacteria can be engineered to produce human insulin to treat diabetics. Genetic engineering can also be used to create and store DNA fingerprints, which can be used for identification purposes.enetic engineering involves altering the genetic code [genetic code: The universal code that DNA or mRNA in every living organism uses to carry information about the sequences of amino acids in its proteins.] of an organism by inserting a gene [gene: The basic unit of genetic material inherited from our parents.

Genetic engineering Genetic engineering is also being used to create BioArt. Some bacteria have been genetically engineered to create black and white photographs. Genetic engineering has also been used to create novelty items such as lavender-colored carnations, blue roses, and glowing fish.f genetic material from the same species or a species that can naturally breed with the host is used the resulting organism is called cisgenic. Genetic engineering can also be used to remove genetic material from the target organism, creating a gene knockout organism.

Genetically modified crops There is general scientific agreement that food on the market from genetically modified crops is not inherently riskier to human health than conventional food. No reports of ill effects have been documented in the human population from GM food.cientists discovered in 1946 that DNA can transfer between organisms. The first genetically modified plant was produced in 1983, using antibiotic-resistant tobacco. In 1994, the transgenic Flavr Savr tomato was approved by the FDA for marketing in the US.

Introduction GMOs, or genetically modified organisms are organisms whose genetic material has been altered using genetic engineering. Genetic engineering is the modification of an organism's phenotype by altering its genetic make-up. Genetic engineering is primarily performed by simple mating or gene recombination.enetically modified crops (GM crops) are those engineered to introduce a new trait into the species. Purposes of GM crops generally include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide).

Genetically modified virus Gene therapy uses genetically modified viruses to deliver genes that can cure disease into human cells. Although gene therapy is still relatively new, it has had some successes. It has been used to treat genetic disorders such as severe combined immunodeficiency.his virus inserted into the heart muscles a gene called Tbx18 which enabled heartbeats. The researchers forecast that one day this technique could be used to restore the heartbeat in humans who would otherwise need electronic pacemakers.

Genetic Engineering Gene targeting is a different technique that uses homologous recombination to change an endogenous gene, and can be used to delete a gene, remove exons, add a gene, or introduce point mutations. An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO).The first GMOs were bacteria generated in 1973 and GM mice in 1974. Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994.enetic engineering alters the genetic make-up of an organism using techniques that remove heritable material or that introduce DNA prepared outside the organism either directly into the host or into a cell that is then fused or hybridized with the host.

Confirmed: DNA From Genetically Modified Crops Can Be Transferred Into Humans Who Eat Them It’s also pretty clear that DNA from food can and does end up in animal tissues and the milk products that people eat. There are studies that show when humans or animals digest genetically modified foods, the artificially created genes transfer into and alter the character of the beneficial bacteria in the intestine.
